Background of IQGAP1 antibody

IQ domain GTPase activating protein (IQGAP) is a ~170 kDa protein that is a target molecule for activated Cdc42 and Rac1. IQGAP binds actin and calmodulin and is an effector for the Rho family of GTPases, providing a direct link between the activated GTPase and the actin cytoskeleton. Additionally, the calmodulin-binding protein IQGAP1 binds stoichiometrically to beta-catenin, an oncoprotein integral to cell-cell adhesion and proliferative signaling, and regulates the association of beta-catenin with the cell-cell adhesion complex.
